When a conduit is in place and an electric heateris put in operation, the heated air will pass through the opening 10 in the panel 9 into the main body portion of the provide a protector l form'ed of suitable stouttextilematerial which will exclude sand anddust and this issotashioned as to provide cover. or closuresections 115 so as to it over and pocket thespouts 13ofthe'conduit, the said covers orclosures being con 7 nected withv or attached I to the connecting q strip 16 which-is of sufiicient length to extend from one end to the other of the conduit 'duit to hold said protector in place.

across or lengthwise of" the outer w all'of said conduit and suitable pliable fastening members 17 are secured tothe covers so that :when' the protector is in place, these fasten-- mg members may be wrapped around the spouts and tied whereby the protector will be securely held in place against the blasts of air and sand or other cleaning substances under pressure,

The conduit being of smaller rwidth than I thepanelwhen the device isassembled in a railway car and the fioorjof the latter poured orlaid, the lower edge of the panelwill .be 'covered and the bottom wall of the, conduit will practically lie upon the upper surface of the floor asclearlyshown in Fig. -1, but since the bottomwalls of the spouts are inside from the bottom, of the conduit, said spouts will be spaced fromthe floor to permit application of the protector.
